Polyamide (PA) is the generic name of polymers synthesized by linking monomers via amide bonds, and various types of PAs with different monomer compositions are known. Distinguishing PA polymers is useful in directing monomer residual testing, product testing, and reverse engineering, but is analytically challenging and cumbersome. To simplify this, we explored the applicability of direct analysis in real time mass spectrometry (DART‐MS) for screening PA polymers.

使用实时质谱法中的直接分析快速鉴定聚酰胺

聚酰胺（PA）是通过经由酰胺键连接单体而合成的聚合物的通用名称，并且已知具有不同单体组成的各种类型的PA。区分PA聚合物可用于指导单体残留测试，产品测试和逆向工程，但分析难度大且麻烦。为了简化此过程，我们探索了实时质谱（DART-MS）中直接分析用于筛选PA聚合物的适用性。
